Application filed April 5, 1905. Serial No. 254,005.

To all whom, t may concern.-

Be it known that I, WILLIAM H. LAUDE, a citizen of the United States, residing at Monticello, in the county of Jones and State of Iowa, have invented new and useful Improvements in Rivet-Cutters, of which the following is a specification.

This invention is a rivet-cutter designed particularly for shearing or cutting olf the ends of rivets when projecting' from a piece of work.

The object ot' the invention is to produce a rivet-cutter characterized by strength and simplicityT and ease in the cutting operation.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan view; Fig. 2, an edge view, and Fig. 3 a section on the line 3 3 of Fig. 1.

The device consists of a pair ot' lever-handles pivoted together, one handle having a head with a hole which is placed over the rivet so that the latter will project through the hole and the other handle having a camshaped cutting edge which shears the projecting edge oi' the rivet when the handles are brought toward each other.

Referring specilically to the drawings, 6 indicates one handle having at the front thereoi' a head consisting of a circular plate 7, having around the edge thereof a raised rim 8, which is cut away on one side, as at 9, to allow the turn of the other handle which carries the cutting edge. The plate 7 has a hole 10, through which the rivet projects when the device is placed thereover in use. The other handle is indicated at 11 and has at the front end a cam-shaped blade 12, whose cutting edge shears across the hole 10. The head l2 is pivoted to the plate 7 by a screw 13, which screws into a threaded hole at the center of the plate 7, said hole being surrounded by a projecting' collar 14, which lits in a circular recess formed in the underside of the head l2.

The plate 7 is comparatively thin, so that when laid upon a piece of work the rivet may be sheared oli' quite close to the surface of the work. The rims 8 and 9 and the collar 14 give the necessary strength to stand the shearing strain, and so permit the plate to be made thinner than would otherwise be the case. Also the collar la forms a bearing' for the head 12, so that the strain ot' the cutting action cornes on the collar and not on the pivot-screw 13. This is an important advantage, since otherwise a heavy bolt or screw would have to be used to stand the pressure.

In operation the handles are opened, so that the end of the rivet will come through the hole 10, and the handles are then closed toward each other, causing the cam edge of the blade to shear across the hole and cut oil' the end ot' the rivet.

I/Vhat I claim as new, and desire to lsecure by Letters Patent. is-- A cutting' implement comprising a pair of pivoted handles one of which has at the head a circular plate provided with a strengthening-rim around the outer edge and an opening therethrough, and a pivot-hole at the center having a projecting collar around the same, and the other ot' which has a head fitting upon the plate within said rim, with a cutting edge which shears across said opening, and a recess on the under side fitting overthe collar.

In testimony whereof l have signed my name to this specilication in the presence of two subscribing witnesses.
